r claims. (01. 139-192) This invention relates to unnrovementsin reeds. for looms, audit. relates more particularly to the construction; and arrangement of reads the. parts ofwhich are made of metal: and which are soldered at the top and bottom of the. reed to hold the same together.

Heretofore, in the. construction of. loom reeds in. which all. the parts are made of metal, it has been customary to provide. at; eachend of the reed relatively heavy end pieces: of the same thickness as the width of the dents of the. reed, but. of a. width considerably greater than the thickness of the dents so as to provide the requisite stiffness at the ends of the reeds. The dents. of the reed, particularly those adjacent the end members, will thus be maintained straight. and unflexed throughout their lengths.

However, there are now in use certain types of looms in which it is desirable and, in some instances. necessary, that the width of the: end 1 member be. reduced to as small a dimension as possible. This, however, introduces difficulties. in the construction and arrangement of the parts of the. structure for the purpose of securing the necessary strength. and rigidity.

The principal object of the present invention is to provide a reed forloomsin. which the width of the end struts thereof, in the direction across the. loom, will be reduced to a minimum.

A further object of the invention is to provide a loom reed, of the character aforesaid, which is so constructed and arranged as to provide adequate strength and rigidity at the ends thereof.

A further object of the invention is to provide a loom reed, of the character aforesaid, which may be inexpensively constructed.

The nature and characteristic features of the invention will be more readily understood from the followin description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure 1 is a rear elevation of a loom reed embodying the main features of the present invention, certain parts being broken away;

Fig. 2 is an end elevation thereof;

Fig. 3 is a fragmentary section taken approximately on the line 33 of Fig. l on an enlarged scale; and

Fig. 4 is a similar section on the line 4-4 of Fig. 2.

It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed 21 without departing from the. spirit of the; invention.

. Referring. to. the drawing, in, the particular emhod iment of the. invention therein shown, the dents 5 are of the: usual form comprising thin fiat strips of metal, the end portions of which are. inserted between: successive convolutions of coil springs; 6- and 7 near the top and bottom of the reed-respectively. There are also provided the. usual strips. 8 and 9: near the top, and strips Hi and. Hi near the bottom, each of segmental cross secti'on, which are inserted between the edgesof' the dents and the outer portions of the successive convolutions of the spacing springs 8 and-1 The reed may also be provided with the usual reinforcing plates i2 and I3, shown only at the bottom, but which, as is well understood, may also be provided at the top of the reed if desired.

' The end struts I4 are relatively thin or narrow in the direction of the Width of the loom being, in the particular embodiment shown in the drawing; approximately double the thickness of the reed dents. Inasmuch as end struts of such thickness, if made thewidth of the dents only, would not afford sufficient support to maintain the dents straight and un-fiexed. The end struts it therefore are each provided with extensions I 5 projecting beyond the plane of the rear edges of the dents, and such projectingportion is prefera-b-Iy'inciihed asat it, near the top and bottom, so that adjacent the ends of the spacing springs 6 and l the end struts It are of a width corresponding to that of the dents of the reeds.

Of course, the front edges of the end struts do not project beyond the plane of the front edges of the reed dents, as otherwise the same would obstruct the free passage of the shuttle through the shed.

.In the usual construction of the soldered reeds, it is customary for the segmental strips 8, 9, l0 and II to extend beyond the end convolutions of the springs and across the faces of the end struts so that, when the solder 2! is applied, the same are secured to the end struts and serve to assist in securing all of the parts in a solid homogeneous mass. However, when the end struts are made relatively thin, for example, approximately double the thickness of the dents, it is not possible to secure in every instance a secure and safe soldered connection at this point.

In the present construction the is provided, at each end of each spacing spring, a pin member I1, having an en arged nead portion l B, which is seated in a compiementally countersunk hole [9 in the end member. Said pins I 4 extend through suitable apertures 20 in the dents 5 adjacent the end struts.

After the various parts are assembled and while held in proper relationship with each other, the top and bottom portions or the reed are soldered so as to secure the various parts thereof, at the places where the solder 2i is applied, into a solid homogeneous mass.

By the foregoing arrangement there is provided a metallic reed in which the parts are fixedly and firmly secured to each other, and in which sufficient rigidity is provided notwithstanding the o! the dents adjacent the ends of the reed, said pins having enlarged head portions seated in complemental apertures in the end struts for retaining said struts in the structure, and the shank portions of said pins being soldered to the end portions of the dents through which they extend.

3. In a textile reed of the all metallic type comprising dents made of thin fiat strips of metal spaced near their end portions by means of coil springs in which the dents are respectively positioned, and end struts extending parallel to the end struts are quite thin in the direction across the loom. Furthermore, the construction is such that the reeds may be inexpensively made without requiring any special equipment other than that commonly used for making ordinary soldered reeds.

It will, of course, be apparent that while the invention is shown and described as applied to a reed for use in a weaving loom, it will also be applicable for the construction and arrangement of various other kinds of reeds, combs, and guides used in various textile operations.

I claim:

1. In a textile reed of the all metallic type comprising dents made of thin fiat strips of metal spaced near their end portions by means of coil springs in which the dents are respectively positioned, the provision of end struts made of metallic strips relatively thin in the direction across the loom, said end struts having projecting portions on the rear sides thereof extending b yond the plane of the rear edges of the dents, and pins extending through apertures in the end portions of the dents adjacent the ends of the reed and having enlarged head portions for retaining said end struts in the structure, and the shank portion of said pins loeing secured to the end portions of the dents through which they extend.

2. In a textile reed of the all metallic type comprising dents made of thin fiat strips of metal spaced near their end portions by means of coil springs in which the dents are respectively positioned, the provision of end struts made of metallic strips relatively thin in the direction across the loom, said end struts having projecting portions on the rear sides thereof extending beyond the plane of the rear edges of the dents, and pins extending through apertures in the end portions dents, the means for securing said end struts in the structure including pins extending inwardly and having enlarged head portions for retaining said end struts in the structure, and the shank portions of said pins being secured to end portions or the dents.

4. In a textile reed of the all metallic type comprising dents made of thin flat strips of metal spaced near their end portions by means of coil springs in which the dents are respectively positioned, and end struts extending parallel to the dents, the means for securing said end struts in the structure including pins extending through apertures in the end portions of the dents adjacent the ends or thereed, said pins having enlarged head portions seated in complemental apertures in the end struts for retaining said end struts in the structure, and the shank portions of said pins being soldered to the end portions of the dents through which they extend.
